Question

The decomposition of ethanol (C2H5OH) on an alumina (Al2O3) surface
C2H5OH(g) → C2H4(g) + H2O(g) was studied at 600 K. Concentration versus time data were collected for this reaction, and a plot of [A] versus time resulted in a straight line with a slope value of 24.00 × 10-5 molL-1s-1.
a. Determine the rate law, the integrated rate law, and the value of the rate constant for this reaction.
b. If the initial concentration of C2H5OH was 1.25 × 10-2 M, calculate the half-life for this reaction.
c. How much time is required for all of the 1.25 × 10-2 M C2H5OH to decompose?
